SPECIFICATION forming part of Letters Patent No. 359,743, dated Ddarch 22, 1887.

Application filed July EG, 1886. Serial No. 909,146. (No model.)

To all whom if, may concern:

Beit known that we, VERNON RorLn and JOHN ROYLE, Jr., both of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful improvement in XVaste and Flushing Talves for WaterCloset Vaults and Gesspools, of which the following is a specification.

Our invention relates to valves whiclrare employed for controlling the outlets from cesspools or privy-vaults, and which are so constructed as to provide an overflow for maiir taining a desired level of water in the cess` pool or vault, or for entirely emptying the same when desired.

In carrying out our invention we employ an outlet-pipe section provided with a valveseat and a pipe having a surrounding ".falve-ring which closes upon the said seat, the said pipe being vertically movable, so as to provide l'or opening the valve when desired.

Theinvention consistsin novel combinations of parts and details of construction, which are hereinafter described, and pointed ont in the claims. 4

In the accompanying drawings, Figure l is a vertical section of a privy-vault having the invention applied thereto, the valve being closed and the overllow in operation. Fig. 2 is a corresponding section with the overflowpipe raised so as to open the valve and empty the vault for flushing purposes. Fio. 3 is a side elevation of a complete apparatus which embodies our invention upon a larger scale. Fig. et is a horizontal section on the plane of the dotted line .fr a', Fig. 3. Figs. 5 and G are, respectively, au elevation of thelower portion of the overflow-pipe and a plan of the valvering which is to be applied thereto, and Fig. 7 is an elevation similar to Fig. 5 with the valverin g in place.

Similar letters of reference designate corresponding parts in the several figures.

A designates the vault, and B theprivy arranged above the same, and having a seat, b, and the 'door b. At the bottom of the vault is the outlet-pipe section C, having at its mouth a daring or taper valve-seat, c, and above this outlet-pipe section is a cage, l), of open construction, comprising at the vtop a guide, d, which is concentric with the valve-seat c.

As best shown in Figs. 3 and 4, the mouth of the pipe-section C has an outwardly-pro` jecting flange, c, )rovided with radial arms c", and the cage D has a base ring or iiange, d', which is recessed on the under side to receive the arms chaud is bolted to them. lVithinthc guide d is a vertically-movable pipe, E, the lower end of which is of a size to enter freely into the outlet-pipe section C, and which is surrounded at a little distance above its lower end by a valvering, c.

The portion of the pipe E which projects below the valve'ring c enters the portion of the pipe-section C below the valvcseat, and is guided thereby to properly center the valve. The lower end of the pipe E may be notched upward, as shown best in Figs. 5 and 7, so as to form downward projections o, between which openings are afforded and which are unconnected at their lower extremities. 1When the pipe is thus constructed, an opening through the valve-seat o will be aiiorded without lifting the pipe entirely clear of the pipe-section C and without depriving the pipe of guidance at its lower end. In the case of a waste-valve for water-closet vaults it is desirable to have the pipe E formed with its downward projee A tions o unconnected at their extremities, because there is less likelihood of paper or other solid substances getting between the circular exterior of the pipe E and the outlet-pipe section G than there would be if the pipe E was slotted near its lower end to form outlet-openings, or if, iu other words, the downward projeotions o were connected by a circular ringlike portion at their lower extremities.

As best shown in Figs. 5 and 7, the pipe E is provided with a circumferential groove, e', which is concave in a vertical direction, and within this groove the valve-ring e, of indiarubber or other elastic material, is held by its contractile elasticity. The pipe E has exten nal vertical ribs, el, which have greater projection from the pipe than the valve-ring e, and consequently the guide d, which is large enough in diameter to receive the ribs e2, permits the valve c to be moved upward with the pipe E directly through and above the guide. he valve-ring e is of course less in external ICC diameter than the internal diameter of the guide d.

In order to provide for preventing the pipe E from being raised normally suiiicient to carry it above the guide d, one of the ribs e2 may have an ol'itwardly-extending stopprojection, c, near its lower end, and the guide (l may have a notch, d2, (shown in Fig. 4,)which receives this projection when the pipe E is turned so as to bring them coincident with each other. Consequently the pipe E, after being` inserted downward through the guide d and turned slightly, is prevented from being raised above the guide until it `is turned back to its position of insertion, which is not likely to be done accidently. At the same time, however, the projection and notch dA2 e provide for removing the valve and overdow-pipe E, when desired,withont descending into the vault.

The pipe E has at the top, on one or each side, an overiiow-opening,j', which is within the liquid seal or trap formed by an outer cir-1 cularwall, j", within which is an annular chamber or well open at the top and an inverted cup, f, immersed in the water in said chainu ber or well, as shown in Figs. 1 and 2.

Then thc pipe Eis in its lower position,

closing the valvering eupon the seat c, it will l retain the level of water in the vault, as shown in Fig. 1, and provides for proper overflow of all water entering through the pipe E,without permitting any gas to ascend from the sewer.

It will be observed that below the trap or liquid seal at its top the pipe E affords a clear` and unobstructed opening or passage downward,and affords no opportunity for the lodgment of any solid matter within it.

Vhenever required to Hush tha sewer, the pipe E may bc raised by means of a rod, E', extending upward near to the floor of the privy and to which access may be had by a removable board or boards, b2, in the floor.

It will be obvious that if the outer wall,'f, of the liquid seal or trap had a true or plain upper edge, paper iioating on the water in the vault would lap over this outer wall and be there retained. To avoid this, I make the upper edge ofthe wall f serrated or with notches, as shown .at-f3, and the upward projections or points form stops to prevent the paper from passing over and lapping upon the inner side of the wallf, as they provide an overflow just below the tops ofthe points or projections.

Although we prefer to employ an india-rubber valve-ring, @which is retained on the pipe E simply by its contractile elasticity, the ring might be secured by screws or otherwise without depending upon its elasticity.

It will be observed that whenever the pipe E is raised the liquid seal at the top thereof retains its water, and hence when the pipe is lowered the gasescape from the sewer is cut oi` as soon as the valve is closed and before the vault iills to au overllow-point.

It is advantageous to give the pi pe E a clear passage through it as large as its diameter at the upper end, because then there is no danger of its clogging.

It is advantageous to make the guide d larger in diameter than the exterior diameter of the pipe Eand to provide for the guidance of the pipe by its projecting ribs e2, because` then the ring-valve maybe sofarranged on the pipe as to shield it within the circumference of the outer edges of the ribs and to pro-` vide for the entire withdrawal of the pipe with the valvenpon it through the guide withf infan outlet without entirel Y raisin@ the i e` o .l e

from the valve-seat and at the same time withont leaving any complete circular portion of the pipe within the valveseat.

Vhat we claim as our invention, and desire to secure by Letters Patent, is A l. The combination, with an outlet-pipesection for a vault or cesspool, provided at the mouth with a valve-seat and surrounded bya cage or strainer having openings in `its sides of such size asto prevent the entrance of such solid 1matter which would [choke the outlet, and having a guide at the top, of a pipe vertically movable in said guide to open and close the outlet, provided with a surrounding valve fitting the valve-seat and proj ectingbelow said valve to be guided in the outlet-pipe section,

and a stop for limiting the upward movement of said pipe, and whichlwill permit its entire withdrawal from the outletepipe section, substantially as herein described.

2. The combination, with the outlet-pipe sec tion provided at the mouth with a valve-seat, and a cage surrounding the outlet and provided opposite the valve-seat with a guide, of the pipe E, vertically movable in said guide and provided with an overflow-opening at the top and having its diameter throughout as large as its diameter at the top, and also provided with ribs ci, the outer edges offwhich make contact with the guide to guide the pipeysaid guide being larger than the exterior diameter of the pipe, and a valve-ring, e, surrounding the pipe below said ribs and which is shielded by the projection of the ribs andris less inexternal diameter than the internal diameter of the guide, so that the pipe with the valve-ring in place may be withdrawn upward through the guide, substantially as herein described.`
